 Abstract: Shielded enclosures installed on circuit boards are fundamentally different to larger shielded enclosures. Typically they have only five sides, the sixth side being the circuit board ground plane to which the shield is soldered. They are also much smaller than conventional shielded enclosures with dimensions in the tens of mm range. Board level shields are typically installed within a larger shielded equipment enclosure or in close proximity to antennas. These constraints make the measurement of the shielding effectiveness of board level shields challenging. As part of the IEEE P2716 project we have been working on techniques to measure how effective these shields are. The talk will concentrate on our new measurement techniques which include statistical descriptions of the shielding rather than simple shielding effectiveness figures in order to address the added complexity of the board level shields' external environment. The latest work on measurements using attachment techniques other than soldering will also be described.  

Biography:

Andy Marvin is Professor Emeritus at the University of York and a Leverhulme Foundation Emeritus Fellow.

He was the founding Technical Director of York EMC Services Ltd, now Eurofins York, and was until December 2017 the Professor of Applied Electromagnetics, in the University of York’s Department of Electrical and Electronic Engineering.

He received his BEng, MEng and PhD degrees in Electrical and Electronic Engineering from the University of Sheffield between 1972 and 1978.

From 1977 to 1979 he was with the British Aircraft Corporation at Filton, Bristol, UK working on antenna design and EMC.

He was appointed to a Lectureship in Electronics at the University of York in the UK in 1979 and promoted to Professor of Applied Electromagnetics in 1995. He was appointed as Technical Director of York EMC Services at its founding in 1995.

He is a Fellow of the Royal Academy of Engineering and an IEEE Life Fellow.

He was Vice-Chairman of the IEEE Std-299 Working Group on Shielding Effectiveness Measurement, and was also Vice-Chairman of the IEEE EMC Society Standards Advisory and Co-ordination Committee. From 1994 to 2015 he was an Associate Editor of IEEE Transactions on EMC.

He has contributed lectures on Antennas and on Shielding to the IEEE EMCS Global University and Chaired its Faculty in 2010.

He is a founder member of the International Steering Committee of EMC Europe conferences, Conference Co-Chair of EMC Europe 2011 (York) and Chair of the International Steering Committee from 2015 – 2018.

He was a member of the UK National Measurement System Advisory Panels on Innovation Research and Development and Materials and Modelling from 2008 to 2015.

His main research interests are EMC measurement and modelling techniques, EMC antennas and electromagnetic shielding measurement and modelling. To date, starting in 1976, he is an author on over 300 papers.
